' appears in Figure 1, to make for easy oiling. 3 The extent to which thehole forming the oil well 21 is exposed when the door is opened is clearly indicated in Fig. 3. The hole forming the oil well 21 is preferably so located that the'upper knuc-kle l i covers the same when the door is closed, see I Fig. 2. :This eliminates the danger of dirt or water entering the oil well. It should be clear from this description that I have provided an extremely simple and highly practical oiling feature for hinges of this kind. The oil well servesas a repository for-enoughoil tojkeep the hinge well lubricated for a long time. F urthermore, there is no danger of oil being'wasted'or the car being messed upby'oildripping from the hinge, becausexof-the fact thatzthepoil well holds the oiluntil it has an opportunity I to work in between. theibearing surfaces. It-

' is evident that thecoutside of the hingewill remain clean because the oil Well allows the surfaces; 25'

oil to be conducted only between the bearing In Fig. 4 I have shown an oil well 21 similarly located but made deeper and provided with a wick 2-2. .By so doing I am enabled to deposit more oil in the well at eachoilingto take :care of lubrication for a longer period i well. as

oftime, thewick serving to absorb the oilan'd'deliver it'to the pintle bearing-2O sparingly. -Furthermore, the wick eliminates" danger of dirt and water collecting in the In Figs. 5+7, I have shown a hingeof a slightly different construction in which the outer hinge member has upper andlower knuckles 23 formed at opposite ends of acover portion 24 to receive the single knuckle 25 formed on the end of the inner hinge member 11'. Thelatter is milled away at the top' and bottom, as indicated at 26,:todefine the I ends of theknuckle 25. The pintle 18 has a drive fit in the holes'19 in the knuckles 23 and a close working fit inthe hole20" in the knuckle 25." An oil well 21- is provided in this case in the inner hinge member 11', at the upper end-of the pintle bearing 20:,:the

same. being exposed when the door is opened,

as indicated in Fig. 5, and covered up and concealed whenthe. cated' in Fig. 6. a

*1. In a hinge comprising an inner hinge member, an outer hinge member, one of said members being provided with knuckles and the other with registering knuckle recesses for hingedly connecting the members, and a ll'ingepintle entered through registering ver- 1 tical holes in said members to complete the hinge connection, an oilwell providedin one of said members comprising a substantially vertical hole provided therein opening ofi the upper knuckle recess and intersecting the hole for the. pintle provided in said member,

wherebyto provide a repository for oil in vertical holes insaid members tocomplete' the hinge connection, an oil Well provided I in one of said members comprising. a substane; tially vertical hole provided therein opening off the upper knucklerecess and-intersecting the hole for the pintleprovided in said member, whereby to provide a repository for oil in direct communication with the pintlehole I to conduct the oil to the latter, said holebe'ing.

so located in said knuckle. recess whereby to be uncovered by the knuckle cooperating with the recess when the hinge is opened, to 1permit-filling with oil and covered bysaid knuckle when the hinge is closed, to prevent entry of dirt or water.

. 3. In a hinge comprising an member, an'outer hinge member, said mem--,

bers' being respectively provided with .uknuckles and registering knuckle recessesfor hingedly connecting thersame,and a pintle entered through registering vertical holes.

provided in said members to'complete the hinge connection, an oil well provided inthe outer 'hinge membercomprising a vertical hole provided therein opening ofl the upper.-

knuckle recess and I intersecting the hole-for the pintle in said member, whereby to provide a repository for oil in direct communication I with the latter.

4. In a pintle hole to conduct the oil" to the hinge comprising an inner-hinge member, an outer hinge member, saidmemhers I being respectively: provided with knuckles and registering knuckle: recesses for hingedly connecting the same, and apintle enteredthrough registering vertical holes provided in said members to complete the hinge connection, an oil well provided -in;the

outer hinge member ,comprising a vertical hole provided therein openingofi the upper, knuckle recess-and intersecting'the hole for the pintle in said membenwherebyrto, pro-J" vide a repository for oil in direct communi- I cation with the pintle hole .to conduct theioil to the latter,said hole being so ,locatedin said knuckle recess whereby tobe uncovered by the knuckle-cooperatingwithlthe recess when" the hinge is opened and covered by said knuckle when thehingeis closed. p

5. In a hinge comprising an inner hinge member, an outerhinge member, said bers being provided withknuckles adapted" to be engaged with one another for hingedly connecting the members, and a hinge plntle entered through registering vertical holes in said knuckles to complete the hinge connec tion, an oil well provided ina knuckle of one .of said members in a position to be covered by the end of a knuckle portionof the other member, the same comprising a substantial- 1y vertical hole provided in said knuckle indirect communieation with the pintle hole to conduottheoil to the latter," said vertical i p holebeing so located whereby to be 'uncovered by the kn ickle portion of the other member Whenthe hinge is opened, to permit filling with oil, and covered by said knuckle portion y when the hinge is closed, toprevent entry I 75 of dirt or,water.
